POWDER HOLDING AND DELIVERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 519,387, dated May 8, 1894.

Application filed July 14,1892.

To aZZ whom it may concern:

Be it known that I, JACOB 0. MICHAEL, a citizen of the United States, and a resident of the city and county of New York, in the State of New York, have invented certain new and useful Improvements in Powder Holding and Delivering Devices, of which the following is a speclfication, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide a receptacle for holding all kinds of powders, of which small quantities are desired to be used from time to time, from which the same may be easily and without trouble delivered in such quantities as desired; and although useful for many other purposes, the same is designed and more particularly adapted for holding tooth powders, and delivering the same upon the brush in fit quantities for use.

This invention consists broadly, of a suitably supported box or receptacle, provided at its lower end with atube, open at the bottom, which projects into the interior thereof, within which tube is a second tube of slightly smaller diameter adapted to move easilyin the first tube, also open at the bottom, and

provided with openings in its sides, adapted to register with similar openings in the sides of the first tube, in communication with the interior of the receptacle, when the inner tube is moved by pressure from beneath; and also further consists in providing a suitable stand of peculiar construction, to be used in supporting such powder receptacle, from which one receptacle when empty may be removed, and a full one substituted therefor.

Said invention is fully disclosed in the following specification, of which the accompanying drawings form a part, wherein similar numerals of reference designate like or equivalent parts wherever found throughout the several views, and in which Figure 1, designates a side view of my improved powder-holding and delivering receptacle in position in my improved support therefor; Fig.2, a rear view of the same; Fig. 3, a view incentral longitudinal section of the lower portion of such receptacle, showing the construction of the delivering mechanism; and Figs. 4 and 5, views in detail, of modi- Serial No. 439,987- (No model.)

of substantially the inverted shape shown.

The box 1, and bottom 2, are each preferably provided with corresponding beads 3 and 4, which fit into one another when the bottom is forced upon the box, in such manner as to hold such box and bottom firmly together, and prevent the same from being taken apart, except by the use of great force or appropriate tools.

Firmly secured in a hole formed in the center of the dome shaped bottom 2, preferably by being made slightly larger than the hole, and sprung into place therein in the manner common in the manufacture of sheet metal goods, is a tube 5, preferably formed of the same thin sheet metal as the box 1 and bottom 2. This tube 5, projects into the interior of the box 1, for a short distance, preferably to about the depth of the dome shaped bottom, 2, as shown; and the sameis open at the outer end, and preferably closed at its inner end bya cover-6, formed integral therewith, or secured firmly thereto in any desired manner. In order to hold the tube 5, firmly in place in the bottom 2, and prevent Wabbling of the same, the central hole of such bottom 2, when first formed therein, is preferably made much smaller than the tube 5, and is then enlarged by forcing outward the surplus metal so as to form a flange 7, surrounding the hole, until the same is of sulficient size to allow the tube 5, to be forced into position therein.

Formed in the side walls of the tube 5,just within the dome of the bottom 2, and extending upward along the tube from the inner side of the bottom to about one third of the height of such tube, are one or more holes or openings 8, preferably of substantially rectangular shape, as shown; and sliding easily IOI) up and down in said tube 5, is an inner tube 9, of such size as to fit snugly therein, and still be capable of movement. This tube 9, 1s open at the outer end, and also preferably at the inner end as well,and is provided with holes or openings 10, formed in the side walls thereof, of substantially the same shape, size and number, as the openings S,in the tube 5, which openings 10, are adapted to register with the openings 8 only when the tube 9, is ralsed from its normal position by being pushed back into the tube 5, as far as it will go; the openings 8, being normally closed by the upper portion of the side walls of the tube 9, as shown in Fig. 3. The tube 9, is of substantially the same length as the tube 5, and is held in place therein, and prevented from falling completely out of such tube 5, when the device is in position with the bottom 2, downward, by any convenient means, preferably by wires 11, which pass through holes formed in such tube 9, just above the openings 10, and also through the openings 8, in the tube 5. These wires 11, are preferably curved upward, and extend nearly to the circumference of the bottom 2, with the interior of the dome of which they are nearly in contact throughout their entire length, as shown, and the same act as agitators to throw down the powder to the openings 8, when the device is operated, as will be more fully explained hereinafter.

Within the tube 9, and resting either on a metallic button 12, supported by the wires 11, or on such wires themselves, is preferably placed a spiral spring 13, the upper end of which bears against the end 6, of the tube 5, in such manner that the tube 9, is kept normally forced out of the tube 5, as far as the wires 11, will allow the same to go, whereby the openings 8, are normally kept closed by the upper portion of thewalls of the tube 9, as hereinbeforo stated.

The frame or support 14:, in which the receptacle or box 1, is held in position to be operated, with the domed bottom 2, downward, as shown in Figs. 1 and 2, may be constructed of any desired material, and of any preferred form, but I prefer the one shown, wherein such frame or support is made of tinned wire twisted into the required shapes. In this form, such support consists of a bottom portion or base 15, provided preferably with short legs 16, on which the device rests, and supporting a shallow removable dish 17, adapted to receive any of the waste powder which may accidentally fall from the tube 9. Supported by this base 15, and extending upto different wires of the standard 17, so as to spring slightly apart to allow the box to be forced into the rings and then close together again so as to grip the same tightly.

The operation of the device is as follows: The box or receptacle 1, having been filled with the required kind of powder, and the bottom 2, having been forced upon the same, until the beads 3 and 4, slip into one another, the same is next forced down into the rings or clasps 1.9, of the support 14, the dome shaped bottom 2,being downward, untilsuch box 1, is in the position shown in Figs. 1 and 2, when the device will be ready for use. When it is desired to obtain powder from the receptacle it is only necessary to lift up the sliding tube 9, by pressing upward against the lower end of the same with the tooth brush, cloth, or whatever other article is used for applying the powder, and as soon as sucn tube 9, is lifted up sufliciently far for the openings 10 to register with the openings 8, powder will fall through both of such openings 8 and 10 into the tube 9, and out of the end thereof, upon the brush, rag or other 1m plement used. If sufficient powder is not obtained at one movement, it may belit'ted again and again, until the desired quantity is obtained. Ordinarily but one movement of the tube 9, is necessary, as the wires 11, rising through the powder serve toshake the same down toward the openings in the tube 5, but should the powderbecome caked high up the box out of reach of the wires 11, it can easily be shaken down by tapping lightly two or three times upon the upper end of the sides of the box or receptacle 1.

In order to compel the openings 8 and 10, to register accurately with one another when the tube 9, is raised, if desired, one or more of the openings 8, may be provided, as shown in Fig. 4, with a central slot 20, at the top thereof, the side lines of which merge by a gentle curve into the side lines. of the opening 8, so that on the tube 9, being raised the wires 11, will be directed into such slot 20, and the openings 8, and 10, thus unerringly and accurately registered.

If desired, in order to give greater range of movement to the shaking wires or agitators 11, one of the openings 8, in the tube 5, may be omitted, and a spiral slot 21, formed in place thereof, as shown in Fig. 5. Through such slot 21, passes one of the wires 11, which is of such size as to slide easily along such slot, consequently when the tube 9, is raised or lowered a rotary movement is given to the tube 9, and to the wires 11, whereby such,

wires are brought into contact with the powder throughout the entire circumference of the box, and shake the same down to the point of the dome shaped cover next to the openings 8.

When all the powder in the box or receptacle 1, has been taken therefrom in the manner described,the same may be removedfrom the support 14, by slipping the same out of TCO the rings or clasps 19, and another full receptacle be substituted therefor; or if desired, the bottom 2, may be taken off, the'box filled, the bottom replaced, and the same receptacle, be replaced in the rings or clasps 19; and this operation, may be repeated indefinitely.

Although I prefer to use a spring, as 13, for keeping the sliding inner tube 9, normally forced out of the tube 5, for the reason that the openings 8, are thus kept closed even when the box 1,is placed with the dome shaped bottom upright, as is frequently the case in shipping such boxes, it is evident that a weight may be substituted for such spring 13, or that 1n some cases both spring and weight may be omitted, and the tube 9, and wires 11, be made of sufficient weight to fall by grav- 1ty intothe position shown in Fig. 3, whenever the receptacle or box 1, is placed with the bottom 2, downward.

It is evident that this improved powder receptacle may be used without the support 14, by being held in one hand during the op erationof delivering powder therefrom, and that the same may be used for holding and delivering powdersof all kinds; and I do not limit myself to the use of the same with the support, or for holding-and delivering any particular kind of powder; neither do Ilimit myself to any particular form of construction, combination or arrangement of thevarious parts of my improved powder holding and delivering device, as it is evident that many changes and modifications, in the construction thereof, other than those named herein, may be made without departing fromthe scope of my invention.
